Pulling in a separate stdlib as a subrepo under the PyPy repo would certainly make this whole process easier.

But you're right, if we track CPython's default branch (3.3) we can make many if not all of the PyPy modifications upstream (until the 3.3rc1 code freeze) instead of in PyPy's modified-3.x directory. Maintaining that modified-3.x dir after every resync can be tedious.
